gauge

I'm trying to use some ready written javascript to make gauge. I'm almost there, but i cannot figure how to manage value captions. Here is how my code works now: And this is how I like it to work: Don't know how to approach to problem. Working with those Math.Pi, Math.cos and Math.sin is just too much for me. var name = "Value"; var value = 17; var gaugeMaxValue = 100; // data to calculate var percentValue = value / gaugeMaxValue; //////////////////////// var needleClient; (function(){ var barWidth, chart, chartInset, degToRad, repaintGauge, height, margin, numSections, padRad, percToDeg,

I'm trying to use Highcharts new solidgauge plugin. http://jsfiddle.net/4zVU8/2/ source code as provided by highchart The gauge accepts three STEP parameters to show different color based on the Data. The problem is that it displays color in gradient and I wanted 1) Green color upto say 20% 2) yellow upto 80% and 3) once value crosses 80% gauge color should be Red . Is it possible? To get a solid color, set the minColor and maxColor options to the same value. To set the color based on a value, just compare in the options: var guageValue = 60; var gaugeOptions = { ... yAxis: { minColor:

Facebook will begin testing hiding like counts, starting in Australia on September 27th, according to TechCrunch. The test will hide the number of likes on a post, only displaying that a post was liked by “[a friend] and others,” instead of displaying the actual number to the public. The limited test is a gauge of whether the feature can improve users’ sense of well-being, and if the experiment is successful, the test may roll out to more regions. “We are running a limited test where like, reaction, and video view counts are made private across Facebook. We will gather feedback to understand

一、简介 Prometheus将所有采集到的样本数据以时间序列（time-series）的方式保存在内存数据库中，并定时保存在硬盘上。时间序列中的每一个样本由以下三部分组成。 指标(metric): metric name和描述当前样本特征的labelsets组成，参考格式如 <metric name>{<label name>=<label value>, ...}； ，其中metric name的命名规则为：应用名称开头_监测对像_数值类型_单位 时间截(timestamp):一个精确到毫秒的时间截； 样本值(value):一个float64的浮点类型数据表示当前的样本值。 二、Prometheus的四种数据类型 2.1 Counter(计数器类型) Counter类型的指标的工作方式和计数器一样，只增不减（除非系统发生了重置）。Counter一般用于累计值，例如记录请求次数、任务完成数、错误发生次数。counter主要有两个方法： //将counter值加1. Inc() // 将指定值加到counter值上，如果指定值< 0会panic. Add(float64) 在Prometheus自定义的metrics监控中，Counter的使用可以参考如下： public class PrometheusMetricsInterceptor extends

本文根据 8 月 11 日 SOFA Meetup#3 广州站 《蚂蚁金服在云原生架构下的可观察性的探索和实践》主题分享整理。现场回顾视频以及 PPT 查看地址见文末链接。 前言 随着应用架构往云原生的方向发展，传统监控技术已经不能满足云原生时代运维的需求，因此，可观察性的理念被引入了 IT 领域。 下面我将会就可观察性在云原生的起源，可观察性发展动力，可观察性与监控的关系，可观察性的三大支柱，社区发展方向及产品现状，以及蚂蚁金服对相关问题的理解及实践进行探讨。 才疏学浅，欢迎拍砖。 为什么云原生时代需要可观察性 可观察性的由来 在云原生语境下的可观察性这个词，最早出现于2017年7月，Cindy Sridharan 在Medium 写的一篇博客， "Monitoringand Observability"[1] 谈到了可观察性与云原生监控的关系。 而在2017年10月，来自 Pivotal 公司的Matt Stine，在接受 InfoQ 采访的时候，对云原生的定义进行了调整，将 Cloud Native Architectures 定义为具有以下六个特质： 模块化 （Modularity） (通过微服务) 可观察性 （Observability） 可部署性 （Deployability） 可测试性 （Testability） 可处理性 （Disposability） 可替换性

How can i draw a following plot in R? Red = 30 Yellow = 40 Green = 30 Needle at 52. Pls help me out as i am in great need. Thanks So here's a fully ggplot solution. Note: Edited from the original post to add numeric indicator and labels at the gauge breaks which seems to be what OP is asking for in their comment. If indicator is not needed, remove the annotate(...) line. If labels are not needed, remove geom_text(...) line. gg.gauge <- function(pos,breaks=c(0,30,70,100)) { require(ggplot2) get.poly <- function(a,b,r1=0.5,r2=1.0) { th.start <- pi*(1-a/100) th.end <- pi*(1-b/100) th <- seq(th

Okay so i've been trying to do this for a couple of days and i am getting no where. So i have the following two images: The First is a RPM Gauge The Second image is a full white graphic representing rpm gauge being full: I want to do the following: ask the user for an RPM input, if for example they enter 1.2 the gauge will fill up as follows: I have the user input working i need help with the animation. Here is what i have tried: I have tried using PorterDuff but it also clips the gauge in the background not just the white bar I've tried splitting the image into little bitmaps and store them

I want to have a simple gauge view where i will define the start value and the end value and have a pointer to show given variable value. So i can show a given value like speedmeter. For example if my the value of a textView is 1300, then next to the textview i want to have this custom meter view animation like this! It is possible? Any existing example code? Another one i found at Evelina Vrabie's blog , used it and worked perfect! Look at Evelina Vrabie's GitHub . It has a gauge library and some samples to interact with. Big thanks to the owner Evelina Vrabie! However it is not working on
